Firefox will only start if I sign in as an administrator. It doesn't connect to the internet, and I can't get to the help screen. I did a refresh but that hasn't help. If I uninstall and then reinstall a new copy correct the problem? How do I save and reinstall my bookmarks and settings? I love Firefox and prefer it over other browsers. But I need to fix it and any help you provide will be very much appreciated. Thank you!

Firefox displays garbled characters, but other browsers do not display garbled characters on the same website.I'm sure it's not a website issue, because more than one website is experiencing garbled text problems. We tried solutions found online, but none of them worked, including completely uninstalling and reinstalling Firefox.

I’m currently facing a very frustrating issue with Firefox. I have been using Firefox for many years, and it is my favorite and most comfortable web browser for my day-to-day work. I rely on it heavily as all my bookmarks and other important details are saved there.

However, over the past few weeks, Firefox has been crashing more than 10 times a day. I have already tried all the troubleshooting steps available in the forums and through AI support, but none of them have resolved the issue. I also tried installing and using the Firefox Beta version, but the problem still persists.

In our environment, other users and devices are not experiencing this issue, so it does not appear to be related to internal firewall or antivirus restrictions.

Could you please help me troubleshoot this issue? I am attaching the error screen that appears after the crash along with the crash report for you

MY PROBLEM IS VERY SIMPLE:"IM TRYING TO OPEN A WEBSITE NAMED SLOW ROADSBUT ITS NOT OPENING AND IT SAYS INTERNAL ERROR 500 SO PLS HELP ME

THANK YOU!

bold text''''bold text' In Settings under Startup, I have check to open all my previous tabs, but when I am shutting down, Firefox wants to close all my tabs before shutting down. If Firefox closes all my tabs on shutdown, then those tabs will not be there next time I start up .... how can I keep my tabs when I shutdown and have them next time I start up

when attempting to login to 53.com credentials are entered, login pressed, login flashes but no login.... as if there is a pop up or something that should occur and doesn't. On edge it works fine, press login and a clock like symbol overlays the login button and then you are in....

I am encountering an issue where, while searching for images on google, the images appear extremely low resolution. When I attempt to open the image in another tab, it remains extremely low resolution and low quality. The issue is not with the images themselves, as I am able to view them on my phone with higher resolution, it is just my desktop that experiences this issue. Please fix it.

I need to uninstal firefox because it is not opening, keep getting message to first close firefox !!! I can not close firefox because I can't get it to open in the first place.

The power went out while I was working and when I turned the computer back on, my Firefox account was logged out and I don't know how to get it back , Every time I try to restore the account it gives me the default account. And thanks a lot

I've asked this before. I'd still like to know why I don't remain logged in, but today, this also happened.

How can you have an expired session, when there was no session?

Normally, when zoom in on a web page in Firefox, the page will adjust so the page content is still visible, by insisting the magnified content is still visible, or a vertical scroll bar is created to reveal the content.

I also run into pages where the content is only visible when the page is 100% or less.

Can this be adjusted?

The site froze while playing a video. It happened multiple times. Is anyone else reporting this kind of behavior on Instagram. I closed the tab, but cpu stress-like side effects remained for a while.
